basically you should register and get your friends/family to sponsor you.... default fundraising goal is $100 per participant... though if you raise less you do not have to make up the difference. You can also have a "team" instead of individual goal.

Sounds like a fun way to raise money, though I'm unlikely to be able to make it myself.

Should also note that this is a national event... and even other participating children's hospitals in the Northeast (ME, CT, etc)... though I can't seem to find a complete list of event locations...
